The part about religion reminds me of an excerpt from the "circular reasoning" wikipedia article.

"-"using the scientific method to judge the scientific method is circular reasoning". Scientists attempt to discover the laws of nature and to predict what will happen in the future, based on those laws. However, per David Hume's problem of induction, science cannot be proven inductively by empirical evidence, and thus science cannot be proven scientifically." https://en.m.wikipedia.org/wiki/Circular_reasoning
